Upgrade your GM LS engine with the Top Street Performance Pro Series Stage 1 Hydraulic Roller Camshaft, engineered for enthusiasts looking to improve horsepower, torque, throttle response, and overall drivability without sacrificing everyday street manners. Designed for GM Gen III and Gen IV LS-based V8 engines, this mild performance camshaft is an excellent choice for daily drivers, weekend cruisers, LS swaps, street trucks, muscle cars, and performance builds seeking a noticeable performance improvement across the usable RPM range.

Featuring a 202°/206° duration at .050, 0.501"/0.501" valve lift, and a 114° lobe separation angle, this Stage 1 camshaft delivers a broad power curve from idle to 5,200 RPM. The profile is designed to improve cylinder filling and engine efficiency while maintaining smooth idle characteristics and strong low- and mid-range torque, making it an excellent upgrade for naturally aspirated LS combinations.

Manufactured from premium 8620 carburized nickel chromium molybdenum steel, this hydraulic roller camshaft provides outstanding durability and wear resistance for demanding street and performance applications. The precision-ground lobes are engineered for reliable valve train operation and long service life, while the 3-bolt cam gear attachment allows installation on compatible Gen III and Gen IV LS engines.

Whether you're building a 5.3L LS truck, refreshing an LS1-powered Camaro, upgrading an LS3 street car, or completing an LS swap project, this Stage 1 camshaft offers an ideal balance of drivability and performance. It's well suited for performance street cars, muscle cars, pickup trucks, restomods, autocross builds, and weekend drag racing applications where improved acceleration and responsive power delivery are the goal.

For best results, install this camshaft with the recommended LS6-style valve springs, verify piston-to-valve clearance, inspect the timing set during installation, and perform ECU tuning after the camshaft upgrade. Always confirm compatibility with your engine's cam sensor, timing components, and VVT or non-VVT configuration before installation.
